2018-05-25Increase default mbuf size and code simplification/cleanupXavier Simonart1-1/+1
mbuf size was setup to achieve the best performance i.e. using the smallest mbuf and not segmenting packets. However this resulted in complex code, much dependent of the way the pmd are working e.g. a change(fix) in recent dpdk i40e implementation caused a 1782 (=1518+8+256) bytes mbuf to be too small to hold a 1518 bytes packets. Hence this change simplifies the mbuf size selection at the price of a potential decreases in performance - as more memory is now used. Except if jumbo frames are used, the mbuf size will now be the same for all modes. The packets will not be segmented except if jumbo frames are enabled. If jumbo frames are enabled, packets are by default segmented, except if the mbuf size is configured big enough in the config file.

2018-04-26Support reading inline jumbo frame and dump themXavier Simonart1-3/+3
Add support for pkt_inline of jumbo frames. Dump the whole packet, and not a truncated packet. This might have a small impact on performance as the memory footprint is increased (by ~640K * number of tasks), resulting in potential higher DTLB misses.

2018-02-13Fix potential crash in rx and tx distributionXavier Simonart1-2/+5
In some (rare) modes, more than 64 packets can be received through one rx function. This is for instance the case of the lat mode. Change-Id: Ie733c927a8e116c679c464f2551768185ef85366 Signed-off-by: Xavier Simonart <xavier.simonart@intel.com>
2018-01-08Fix stacking of rx receive functionsXavier Simonart1-3/+8
PROX can stack different RX functions, so that they are executed after each other. This feature is for instance used to dump packets or to print distribution of receive packets, without influencing the performance of the rx functions when no dump or print is needed. The previous implementation was wrong and causing some of the stacked functions not to be executed. This was causing for instance issues in latency measurement after enabling dumping packets.

2017-11-15Add support for nop mode with l3 submodeXavier Simonart1-1/+0
The l3 submode was not supported in nop mode, as the nop mode uses some specific nop thread (and not generic). When L3 is specified, the nop mode must use the generic thread. In addition the l3 submode is implemented differently than other submodes. It is not supported through task_init structures (i.e. each task does not have to explicitely tell that it supports l3 submode). But this prevented to run both a nop with no submode and a nop with a l3 submode. Note that nop with l3 is usually not very useful - it handles arp (requests and response) but as nop, it does not swap IP addresses. So with a real switch, the packets transmitted will be received back... and l3 mode is usually mainly usefull when using a switch. However, there is at least one nop mode where l3 submode makes sense: when the nop does not transmit. In such cases, for instace used in conjunction with a gen l3, the nop receives all packets and forward the arp requests and responses to the master for handling.

2017-07-14Adding PROX(Packet pROcessing eXecution engine) VNF to sampleVNFDeepak S1-0/+247
JIRA: SAMPLEVNF-55 PROX is a DPDK-based application implementing Telco use-cases such as a simplified BRAS/BNG, light-weight AFTR... It also allows configuring finer grained network functions like QoS, Routing, load-balancing... (We are moving PROX version v039 to sampleVNF https://01.org/intel-data-plane-performance-demonstrators/prox-overview) Change-Id: Ia3cb02cf0e49ac5596e922c197ff7e010293d033 Signed-off-by: Deepak S <deepak.s@linux.intel.com>
